You see a basic error message "Could not connect to localhost:143". So
test that without using additional software. Foremost consult the
maillog, in this case the log content produced by dovecot. And test
connectivity on the lowest level.

echo QUIT | openssl s_client -connect localhost:143 -starttls imap
I'm getting what appears to be help file with various options when trying to
run the above commad

Can we guess that you don't offer TLS for IMAP connections?

That must be successful first. You can too test "lsof -i :143" or "ss
-tulpen | grep 143". And tail your maillog.

Running lsof -i :143, I get:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
dovecot 1576 root   37u  IPv4  32014      0t0  TCP *:imap (LISTEN)
dovecot 1576 root   38u  IPv6  32015      0t0  TCP *:imap (LISTEN)

Running ss -tulpen | grep 143 :

tcp    LISTEN     0      100       *:143                   *:*
users:(("dovecot",pid=1576,fd=37)) ino:32014 sk:ffff913e953e2e80 <->
tcp    LISTEN     0      100      :::143                  :::*
users:(("dovecot",pid=1576,fd=38)) ino:32015 sk:ffff913b2e90a100 v6only:1
<->

So port 143 is listening. Are we back to the point that your DNS or NSS is broken so that even

telnet localhost 143

fails while

telnet 127.0.0.1 143

is successful?

Thanks!!
